T 0 all whom it may concern:

Be it known that I, lViLLiAM Enswonrii J onus, citizen of the UnitedStates, residing at Vashington, District of Columbia, have inventedcertain new and useful Improvements in Cotton-Seed Hullers, of which thefollowing is a specification.

This invention relates to cotton seed hullers and the object of theinvention is to provide improved mechanism for removmg the hulls fromcotton seed and as far as possible leaving the kernels unbroken, Withoutthe necessity of first removing the lint from the seed.

\Vith this object in view the invention consists in the improvedconstruction, arrangement and combination of the parts of the mechanismfor this purpose which will be hereinafter fully described and afterwardspecifically claimed. a

In the accompanying drawings :Figure 1, is a side elevation of themachine partly in section. Fig. 2 is a vertical sectional view of theinterior mechanism. Fig. 3 is a face view of a portion of the lower oneof the burs provided with curved ridges. Fig. 4 is a face view of aportion of the upper bur provided with radially extending straightridges. Fig. 5 is an edge view of the bur shown in Fig. 3, and Fig. 6 isan edge view of the bur shown in Fig. 4.

The mill consists of the hopper 1 of any ordinary construction on whichis a shaft 2, which is mounted in a hollow structure 3, provided with aspiral feed device 4. and made rigid with a horizontal disk 5. The lowerbur 6, Fig. 3, is bolted to said disk and rotates therewith, and withthe shaft. Said bur 6 is provided on its face with the curved ridges 7and its inner edge is provided with the ridges 8, the spaces betweenwhich permit the seed to pass between the burs as will be hereinafterexplained. The bur 9 (Fig. 4t) is located above the bur 6, and may beprovided with any suitable device such as the bolts 10 for adjusting itsposition. The said bur 9 is provided with the ridges 11, which extend innearly radial directions, being tangential to a very small circle whichwould be concentric with the shaft, the inner edge of said bur beingprovided with the serrations 11 which are alternately high and low.

The seed having the lint thereon is placed in the hopper 1 and the shaft2 is rotated by any suitable means, as for instance by power applied togear 13. The spiral feed 3, causes the linty seed to pass down to theinner edges of the burs 6 and 9 and through the central opening of bur6, landing on bur 9 at its inner edge at which point the seed is caughtby the serrations 8 and 12 of the burs 6 and 9, and are drawn betweenthe burs. As the bur (3 rotates the seed is rolled between the two bursand the lint thereon is finally caught in and between the ridges of theburs and pulled in opposite directions, thereby exerting a strain uponthe hull of the seed, which strain causes the hull to split apart andleave the kernel in a whole state. The kernels, and the hulls with lintattached thereto, finally pass beyond the outer edges of the burs andmay be separated by any suitable means.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States is 1. A mechanicalmeans for removing the hulls of linty seed from the kernels consistingof an annular rotating bur and an annular stationary bur, one bur beingprovided with a single continuous series of tangentially curved ridgesand intervening grooves, all beginning at the outer edge of the bur, andextending to the inner edge of the bur, and a plurality of interveningsimilarly curved ridges of equal length between each adjacent pair offull length ridges, said intervening ridges terminating at equaldistances from the inner edge of the bur, the other bur being providedwith a single continuous series of straight tangential ridges andintervening grooves, all beginning at the outer edge of the bur, saidseries of straight ridges comprising regularly spaced ridges extendingto the inner edge of the bur, ridges intervening substantially centrallybetween said regularly spaced full length ridges, but terminating at aregular distance from the inner edge of the bur, and ridges between saidintervening ridges terminating still farther from the inner edge of thebur.

2. An annular bur for cotton seed hulling machines provided with asingle continuous series of straight tangential ridges and in terveninggrooves, all beginning at the outer edge of the bur, said seriescomprising regularly spaced ridges, all running at substantially thesame angles to the radii, extend- 111g entirely across the bur to theinner edge thereof, and a plurality of intervening similar ridgesbetween each adjacent pair of full length ridges terminating at pointsdistant from the inner edge of the bur, said intervening short ridgesbeing of different lengths and comprising in each section between fulllength ridges, a central ridge extending sub stantially threefourthsacross the bur, ridges substantially central between the said centralridge and each full length ridge extending substantially one-half acrossthe bur, and still shorter ridges between each threetonrths length ridgeand each half length ridge, and each half length ridge and full lengthridge, the grooves intervening between the ridges extending t'roin theouter edge of the bar to the inner ends of the short intervening ridges,from which points they merge into wide grooves between adjacent fulllength ridges, extending to the inner edge of the bar.

In testimony whereof I aflix my signature in presence of two witnesses.
